Description

Technical Field

[0001] This utility model relates to the field of safety hook technology, and in particular to a movable, easy-to-remove safety hook device. Background Technology

[0002] In today's rapidly developing industrialization, working at heights has become commonplace in many construction projects, and the use of safety belts is crucial in such operations, especially when inspecting and maintaining crane booms on high-altitude crane trusses. However, existing safety belt hook structures have significant shortcomings: each time the safety belt passes a railing post, the post obstructs the hook, preventing it from passing directly without being unhooked. Therefore, operators must detach the hook from one side of the post and reattach it to the other side to allow the safety belt to cross the post. If the safety belt needs to cross railing posts multiple times, workers must frequently detach and reattach the hook, which is not only cumbersome and inconvenient but also carries the risk of accidental falls, potentially leading to serious accidents. Therefore, the potential safety risks in this process cannot be ignored.

[0003] Patent CN216703211U discloses a non-removable safety hook and a safety belt with buffer for easy lateral sliding. When the non-removable safety hook is hung on a crossbeam and moves along the crossbeam, it can pass through a side support bar without removing the hook. However, after passing the side support bar, the safety hook can only move in one direction and cannot move backward past the side support bar. At the same time, since the opening of the non-removable safety hook can only be opened by the locking strip, and the locking strip opens approximately perpendicular to the hook, it is not easy to hang the non-removable safety hook on the crossbeam by applying force to the crossbeam alone. In fact, the operator may need to bend the locking strip to a certain angle to hang the non-removable safety hook on the crossbeam, which is very inconvenient. Utility Model Content

[0004] In view of this, the present invention aims to propose a movable, non-removable, convenient safety hook device, which not only eliminates the hassle of frequently removing and attaching safety belt hooks, but also effectively reduces the risk of accidents, making high-altitude operations safer and more efficient.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A movable, easy-to-use, and safe hook device includes a base, a hook, and an anti-detachment rod. One end of the hook is connected to the base, and the other end is detachably in contact with the anti-detachment rod. The end of the anti-detachment rod away from the hook is rotatably connected to the base via a pin. When the anti-detachment rod is subjected to a rightward external force, it can rotate to the right along the pin. When the external force disappears, the pin automatically rotates back, driving the anti-detachment rod back to its initial position. A self-rebound rotating shaft is provided in the middle of the anti-detachment rod, dividing it into two parts: an upper first rotating rod and a lower second rotating rod. The first and second rotating rods are rotatably connected via the self-rebound rotating shaft. When the first rotating rod is subjected to a forward or backward external force, it can rotate forward or backward along the self-rebound rotating shaft. When the external force disappears, the self-rebound rotating shaft automatically rotates back, driving the first rotating rod back to its initial position.

[0006] Furthermore, the base is provided with a through hole for attaching a rope, and a limit baffle is also provided on the base. The limit baffle is located on the left side of the second rotating rod, and the lower end of the limit baffle is connected to the base.

[0007] Furthermore, the hook is welded to the base as a single unit.

[0008] Furthermore, the pin has a built-in self-rebound device. When the pin is subjected to external force, it can rotate along its central axis. When the external force disappears, the pin can automatically return to its original position.

[0009] Furthermore, a limit stop is rotatably connected to the upper end of the hook, and the limit stop can rotate along the hinge point installed on the hook when subjected to external force.

[0010] Compared with existing technologies, the movable, non-removable, convenient safety hook device of this utility model has the following advantages: The movable, non-removable, convenient safety hook device of this utility model is safe and reliable, effectively protecting workers at heights; it eliminates the need for frequent removal and re-attaching of the safety hook during high-altitude operations, improving both work efficiency and significantly enhancing operational safety; the hook device is not only ingeniously structured and easy to use, but also offers superior safety, providing robust safety guarantees for both high-altitude operations and various hooking needs in daily life.

[0011] (1) When using the hook device described in this utility model on the railing, you only need to press the anti-detachment bar on the railing. The anti-detachment bar will rotate inward along the pin shaft under the action of external force, thereby opening the hook and allowing the railing to enter freely. When the external force disappears, the pin shaft will rotate back, thereby restoring the anti-detachment bar to its original state.

[0012] (2) The anti-detachment rod includes a first rotating rod and a second rotating rod. A self-rebound pivot is provided between the first rotating rod and the second rotating rod, and the rotation directions of the first rotating rod and the second rotating rod are different. The hook device described in this utility model can enter the main load-bearing structure of the railing through the inward rotation of the second rotating rod, which can play a good role in locking and securing. When passing through the uprights (or side supports) on the railing, the rotation of the first rotating rod will not drive the rotation of the second rotating rod. Therefore, the first rotating rod ensures that the hook device passes smoothly through the uprights on the railing while ensuring that the second rotating rod is securely attached.

[0013] (3) The anti-detachment rod is equipped with a self-rebound rotating shaft, which makes the hook device convenient. The hook device can rotate freely with the shape of the railing post, so that the hook can pass through without obstruction. When the hook passes through the post on the railing, it can achieve two-way passage, that is, it can move forward or backward, truly achieving the effect of being movable and not needing to be removed.

[0014] (4) The hook device can be easily hung on the railing. When it encounters the railing post, the self-rebound shaft on the anti-detachment bar will rotate smoothly, driving the first rotating rod to rotate, thereby ensuring that the safety hook device passes the post smoothly; afterwards, the self-rebound shaft quickly returns to its original state, and the anti-detachment bar also automatically returns to its original position.

[0015] (5) The hook and the base of this utility model are welded together, making the connection between the hook and the base firm and reliable, effectively improving the safety and reliability of the hook connection;

[0016] (6) The base is equipped with a convenient perforated structure, which makes it easy to hang ropes. It also has a limiting structure to prevent the anti-detachment rod from coming off, which effectively prevents the rod from coming off and improves safety and practicality.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This utility model discloses a movable, non-removable, convenient, and safe hook device, suitable for high-altitude operations, especially for work situations requiring inspection and movement on high-altitude crane trusses. The device is movable, requires no removal, and is convenient and safe, making operations safer and more worry-free, allowing for greater ease and freedom of movement. It is suitable not only for professionals working at heights but also for workers performing high-altitude maintenance. The device is safe, convenient, and efficient, allowing for easy movement without frequent removal, providing a one-stop solution to high-altitude work problems.

[0025] Example 1

[0026] like Figure 1As shown, this utility model is a movable, easy-to-use, and safe hook device, including a base 1, a hook 2, and an anti-detachment rod 3. One end of the hook 2 is connected to the base 1. Preferably, the lower end of the hook 2 is welded to the base 1 as a whole, so that the two are as one, which can withstand the specified strong tensile force, and is stable and reliable. This improves the reliability of the connection between the hook 2 and the base 1, thereby effectively improving the safety of the hook 2 connection. The other end of the hook 2 is detachably in contact with the anti-detachment rod 3. The end of the anti-detachment rod 3 away from the hook 2 is rotatably connected to the base 1 via a pin 5. When the anti-detachment rod 3 is subjected to an external force to the right, the anti-detachment rod 3 can rotate to the right along the pin 5, causing the upper end of the anti-detachment rod 3 to separate from the hook 2. When the external force disappears, the pin 5 automatically rotates back, which can drive the anti-detachment rod 3 to rotate back to the initial position. A self-rebound rotating shaft 4 is provided in the middle of the anti-detachment rod 3, which divides the anti-detachment rod 3 into two parts, including the upper first rotating rod 6 and the lower second rotating rod 7. The first rotating rod 6 and the second rotating rod 7 are rotatably connected via the self-rebound rotating shaft 4. When the first rotating rod 6 is subjected to an external force in the forward or backward direction, the first rotating rod 6 can rotate forward or backward along the self-rebound rotating shaft 4. When the external force disappears, the self-rebound rotating shaft 4 automatically rotates back, which can drive the first rotating rod 6 to rotate back to the initial position. The self-rebound rotating shaft 4 is existing technology. In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0027] The pin 5 has a built-in self-rebound device. When the pin 5 is subjected to external force, it can rotate along its central axis. When the external force disappears, the pin 5 can automatically return to its original position. The self-rebound device is existing technology.

[0028] The central axis of the springback shaft 4 and the central axis of the pin 5 form an angle, preferably 90°. Therefore, the rotation direction of the springback shaft 4 is different from that of the pin 5. Figure 1 For example, the self-rebound shaft 4 can only rotate in the forward and backward direction, while the pin 5 can only rotate in the left and right direction.

[0029] When the movable, non-removable, convenient safety hook device needs to be suspended on the railing, only a rightward force needs to be applied to the anti-detachment rod 3, causing it to rotate along the pin 5. Since there is an angle between the central axis of the self-rebound rotating shaft 4 and the central axis of the pin 5, regardless of whether the force is applied to the first rotating rod 6 or the second rotating rod 7, the anti-detachment rod 3 will remain in a straight line as it rotates along the pin 5. With the rotation of the anti-detachment rod 3, the upper end of the first rotating rod 6 separates from the hook 2, thus smoothly opening the hook 2 and allowing free access to the railing. After the movable, non-removable, convenient safety hook device is suspended on the railing, the force applied to the anti-detachment rod 3 disappears, at which point the pin 5 automatically rotates back to its original position, simultaneously driving the anti-detachment rod 3 back to its initial position. It should be noted that the external force applied to the anti-detachment rod 3 can be a force exerted manually (the first type of force), or it can be the force exerted by the railing on the anti-detachment rod 3 by pressing it against the railing (the second type of force). The second type of force will be explained below. When the force is the force exerted by the railing on the anti-detachment rod 3, as the railing presses against the anti-detachment rod 3 and the force continues to increase, pressing the anti-detachment rod 3 against the railing, the gap between the upper end of the first rotating rod 6 and the hook 2 will gradually increase until the railing smoothly enters the movable, non-removable, convenient safety hook device. Once the movable, non-removable, convenient safety hook device is suspended on the railing, the force exerted by the railing on the anti-detachment rod 3 disappears. At this point, the pin 5 automatically rotates back to its original position, simultaneously driving the anti-detachment rod 3 back to its initial position.

[0030] When the movable, non-removable, convenient safety hook device passes the railing post, the first rotating rod 6 contacts the post and continues to move the movable, non-removable, convenient safety hook device forward. The railing post will then exert a force on the first rotating rod 6. At this time, the first rotating rod 6 is subjected to force and rotates along the self-rebound shaft 4, causing the upper end of the first rotating rod 6 to separate from the hook 2, thereby successfully opening the hook 2. Because the central axis of the self-rebound rotating shaft 4 and the central axis of the pin 5 form an angle, when the first rotating rod 6 rotates, the second rotating rod 7 will not rotate in the same direction as the first rotating rod 6. Instead, as the first rotating rod 6 rotates, the second rotating rod 7 will form an angle with the first rotating rod 6 with the self-rebound rotating shaft 4 as the angle. As the railing post comes into contact with the first rotating rod 6, the gap between the upper end of the first rotating rod 6 and the hook 2 will gradually increase until the movable, easy-to-remove safety hook device successfully passes the railing post. After the movable, easy-to-remove safety hook device passes the railing post, the force exerted by the railing post on the first rotating rod 6 disappears. At this point, the self-rebound rotating shaft 4 automatically rotates back to its original position, while simultaneously driving the first rotating rod 6 to rotate back to its initial position, so that the anti-detachment rod 3 returns to a straight rod state. This allows the anti-detachment rod 3 to automatically return to its upright position and play an anti-detachment role. The structural features of the anti-detachment rod 3 effectively avoid the frequency of repeatedly attaching and detaching the safety hook during work, improving safety during high-altitude operations.

[0031] Since the part of the hook 2 opposite to the first rotating rod 6 does not limit or obstruct the first rotating rod 6, the hook device of this utility model can achieve bidirectional passage when passing the railing post, that is, it can move forward or backward, truly achieving the effect of being movable and requiring no removal.

[0032] The base 1 is provided with a through hole for attaching a rope, which can be easily attached to the rope. The base 1 is also provided with a limit baffle 8, which is located on the left side of the second rotating rod 7. The lower end of the limit baffle 8 is connected to the base 1. When the anti-detachment rod 3 is accidentally subjected to force and rotates to the left, the left side of the limit baffle 8 can abut against the outer wall of the second rotating rod 7, effectively preventing the second rotating rod 7 from rotating further, thereby effectively preventing the anti-detachment rod 3 from detaching. It is safe and practical.

[0033] The hook 2 is made of alloy steel, which can withstand a considerable amount of tensile force to ensure safety.

[0034] Example 2

[0035] The structure is basically the same as in Embodiment 1, except that the upper end of the hook 2 is rotatably connected to a limiting stop 9. When subjected to external force, the limiting stop 9 can rotate along the hinge point installed on the hook 2. Two limiting stop 9s are symmetrically arranged, one on the front and one on the back of the hook 2. When the railing being traversed by the worker is vertical, the worker rotates the limiting stop 9 so that its lower end blocks the outer wall of the first rotating rod 6. In this case, even if an accident such as a fall causes the hook device to pass over the railing post, it can prevent the hook device from directly passing along the railing, ensuring that the hook device is stopped at the railing post, effectively improving safety. When the hook device of this invention passes over the railing post, the worker only needs to rotate the limiting stop 9 so that it does not obstruct the first rotating rod 6, thus achieving bidirectional passage and realizing a movable and unremovable effect.

[0036] When the railing that the staff is passing through is horizontal, the staff can choose not to use the limiting plate 9 for secondary limiting protection. At this time, the limiting plate 9 only needs to be rotated so that the lower end of the limiting plate 9 rotates to both sides of the outer wall of the hook 2, so as not to block the first rotating rod 6. When the hook device described in this utility model passes through the railing post, it can realize bidirectional passage and achieve the effect of being movable and not needing to be removed.

[0037] The hook device described in this utility model is mainly designed for use in high-altitude operations, especially in work environments where workers need to move back and forth at heights. When working at heights, simply hang the hook device on the railing. When passing over the railing post, the first rotating rod 6 on the anti-detachment rod 3 is subjected to force and rotates along the self-rebound shaft 4, allowing the safety hook to pass smoothly over the railing post. Then, the self-rebound shaft 4 returns to its original position, causing the anti-detachment rod 3 to automatically return to its original position and play an anti-detachment role. This avoids the frequency of repeatedly attaching and detaching the safety hook during work, thus improving safety.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
